LOCOMOTIVE REVOLVING CRAN E.

SPECIFICATIOIYT forming part of Letters Patent No. 682,703, datedSeptember 1'7, 1901.

Application filed December 26, 1900. Elorial No. 41 107. (No model.)

To all "whom, it may concern;

Be it known that I, FRANK E. HULETT, a

. resident of Akron Summit county, Ohio, have A further object of myinvention is to pro-' vide a crane of this character comprisingimprovements in the construction and arrangement of the hoisting'andmotive machinery,

whereby the working of the crane is greatly facilitated and aconsiderable reduction is secured in the cost of operating-the same.

My invention therefore consists in providing means for steadying andretaining. the crane on the track of a trestle or similar structure bycoupling the truck thereof to a movable ballast or counterweight.

' My invention also consists in constructing a crane of this characterprovided with a motive engine and a hoisting-engine, each capable ofvoperating independently of the other, and meansfor supplying both of theengines from the same boiler or steam-s11 pply.

My invention further consists in the fea tures of construction andcombination of parts hereinafter fully described in the specification,pointed out in the claims, and illustrated in the drawings.

The locomotive-cranes to which my invention particularly relates aredesigned to travel on standard-gage tracks, and are used for excavatingcoal, ore, or other material and loading it into cars. This employmentgenerally necessitates that the tracks upon which the crane travelsbeelevated upon a trestle or similar structure. Heretofore greatdifficulty has been experienced when operating a crane upon a trestle inpreventing the crane from being overturned by the weight of {the load inthe grapple-bucket or through the reaction caused by the suddenreleasing of the load from the grapple-bucket. As it is impossible toblock up or prop the crane on a trestle in the same manner as can bedone on the level ground, this difficulty has been overcome to someextent by clamping the truck of the crane to the rails; but this methodhas been found cumbersome and ineXpedient.

By my invention I provide means located at each of the four corners ofthe framework of the truck of the crane adapted to engage the adjacentcorners of cars coupled at either end of the said crane. By these meansthe weight of the cars used for hauling the material excavated may beutilized as a ballast or counterweight to prevent theoverturning of thecrane. A great advantage of thus steadying the crane by the weight of anadjacent'tender or car coupled thereto results from the fact that thestability of the crane will be the same whether the crane is moving orstationary upon the tracks. The crane can'therefore be used forexcavating atone place and filling in at an adjacent place withoutloading the material into cars, which would be impractical in case thetruck of the crane had to be clamped to the rails each time thegrapple-bucket was swung.

Referring to the drawings, Figure I represents a side elevation of mycrane. Fig. II shows afsection on lines II II, Fig. I. Fig. III is asection on lines III III, Fig. I. Fig. IV is an enlarged view of thesheaves. Fig. V is a sectional view on lines V V, Fig. IV. Fig. VI is anenlarged view showing the swivel-joint in the steam-pipe connecting theboiler and motive engine. Fig. VII is an enlarged view of a portion ofthe rod for operating the reversing mechanism of the motive engine.

Again referring to the drawings, a represents the truck of the crane,which is mounted.

in the usual way upon suitable sets of wheels a. At each of the fourcorners of the truck are secured the arms I), b,-b and 6 These armsproject beyond the respective ends of the truck a sufficient distance topass under boiler e, an engine f, and the standards g and g, whichsupport a shaft 9 On the shaft g are loosely mounted the sheaves h, t',and

j. The sheaves h and j are provided with clutch members it and j forsecuring them so as to revolve with the shaft g The shaft g isoperatively connected with the engine fby means of a gear-wheel g whichis rigidly mounted on the shaft g and a gear Z, which is connected inthe usual way with the 10 piston-rod of the enginef. A steam-pipe fconnects the boiler c with the hoisting-enginef. Between the sheaves hand z a bar m is mounted so as to revolve freely on the shaft 9?. Thesheaves h and z are provided with lugs 7L2 and t respectively. When thesheave h is revolved, it will make about one turn and will then pick upthe bar m and will carry it around another revolution until the barengages the lug t on the sheave t and the two sheaves will revolvetogether. Likewise, when the sheave h is reversed it will revolve once,then pick up the bar on, and then turn once more before engaging thesheave 2'.

To the floor of the truck a is secured a double-cylinder engine 19,which is connected in the usual way with the driving-wheels of thetruck. A reversing-valvet is secured to the floor of the truck and isconnected with the cyl- 0 inder of the engine by pipesp. A steam-pipe 6leads from the boiler e to the upper part of a vertical pipe or cylinder0, which passes through the center of the turn-table. The pipe 6 issecured to the cylinder 0 by means of a 3 5 swivel-joint 0, which allowsthe upper portion to turn while the lower portion remains stationary. Asteampipe e connects the lower portion of the cylinder 0 with areversingvalve t. A lever r is mounted on the platform 0, one end ofwhich is connected to a rod 0", which passes down through the cylinder 0and is connected at its lower end to a bellcrank lever s. The openingsin the cylinder 0 are well packed to prevent the escape of 3 steam. Thebell-crank lever is in turn connected to a rod 5, which is secured tothe operating-arm of the reversing valve.- This allows the engine to bestarted or reversed from the platform 0.

As a means for reversing the driving-engine I have shown areversing-valve located between the steam-supply and cylinders of thedriving-engine; but I do not claim this as part of my invention, as mymeans for actuating the reversing mechanism can be adapted to operateany style of reversing mechanism, either reversing valves or links.
